各种各样的安装教程五花八门都不一样。要注意摄像头型号的区别

似乎有好几种方法？ Jetson Nano versions这个人的方法提到的比较多？

参考这个

怎么还对cuda版本有要求

最后采用的方法

These are packages for using Intel RealSense cameras (D400 series SR300 camera and T265 Tracking Module) with ROS.
Method 1: The ROS distribution:
Ubuntu
realsense2_camera is available as a debian package of ROS distribution. It can be installed by typing:
realsense2_camera is available as a debian package of ROS distribution. It can be installed by typing:

sudo apt-get install ros-$ROS_DISTRO-realsense2-camera

This will install both realsense2_camera and its dependents, including librealsense2 library and matching udev-rules.

Notice:

The version of librealsense2 is almost always behind the one availeable in RealSense™ official repository.
librealsense2 is not built to use native v4l2 driver but the less stable RS-USB protocol. That is because the last is more general and operational on a larger variety of platforms.
realsense2_description is available as a separate debian package of ROS distribution. It includes the 3D-models of the devices and is necessary for running launch files that include these models (i.e. rs_d435_camera_with_model.launch). It can be installed by typing: sudo apt-get install ros-$ROS_DISTRO-realsense2-description

方法2

网上各种零散的方法讲的都是方法2
方法2分为两个步骤
不管怎么样肯定是先装驱动 再装ros连接依赖
然后各自又有演变出的不同方法，具体内容可参考上面连接
